Note (1) For details on other error log information, refer to the Operation Manual, Construction of Networks: SECTION 8 Troubleshooting.

(2)An error will occur in the following CPU Units when the automatic clock adjustment function is executed under the conditions shown in the table.

CPU Unit

Conditions

 

 

CPU Units manufactured on or

When the CPU execution mode is set to other

before January 31, 2003 (lot num-

than normal mode (priority peripheral servicing

bers 030131 or earlier):

mode, parallel processing with synchronous

CJ1G-CPU@@H

memory access mode, or parallel processing

CJ1H-CPU@@H

with asynchronous memory access mode).

CS1G-CPU@@H

AND

CS1H-CPU@@H

When the CPU Unit operating mode is set to

 

RUN or MONITOR mode.

 

 

(3)The manufacturing date can be determined from the lot number on the side or top corner of the CPU Unit.

(4)The lot numbers are as follows:

YYMMDDnnnn, in which YY indicates the last two digits of the year, MM the month, DD the day, and nnnn the serial number.
